WooCommerce development: a fast, custom online store
WooCommerce turns WordPress into a complete online store, but a store that actually sells needs far more than an activated plugin: a structured catalogue, a frictionless checkout, payment and shipping options suited to your markets, and performance that holds when traffic rises. Our WooCommerce development service covers building custom stores and taking over existing ones.
It is aimed at retailers, brands, B2B distributors and makers who want a store they control, with no commission on sales and none of the limits of a hosted platform.
We work on the theme and WooCommerce templates, custom plugin development, payment gateway configuration (Stripe, PayPal, bank solutions), shipping rules, taxes, as well as synchronisation with an ERP, CRM or inventory system. Performance is addressed from the start: queries, caching, images, hosting.
When do we step in?
Launching an online store
You already sell in-store or on marketplaces and want your own channel. We design the catalogue, product pages, checkout, payments and shipping.
Your WooCommerce store is slow
Product pages taking several seconds, a sluggish cart, an unusable admin: we audit queries, plugins, caching and hosting to get response times back to acceptable levels.
You have a complex catalogue
Variable products with many variations, bundled products, prices per customer group, B2B catalogue with quotes: WooCommerce can do it, provided it is structured and often complemented by development.
You need to connect your back office
Stock and order synchronisation with an ERP, accounting export, automatic dispatch to a carrier or fulfilment provider through the WooCommerce REST API.
You sell internationally
Multiple currencies, per-country taxes, WPML or Polylang for product pages, shipping rules per zone: multi-country selling is prepared in the configuration and the theme.
How we work
- 1
Commercial and technical scoping
We clarify your catalogue, markets, payment methods, carriers, pricing rules and existing management tools. This step avoids surprises at integration time.
- 2
Purchase journey design
Catalogue structure, filters, product page, cart, single or multi-step checkout, customer accounts, transactional emails. Every screen is designed to convert.
- 3
Development
Custom WooCommerce theme or template adaptation, specific plugins built with WooCommerce hooks, payment gateways configured in test mode then production.
- 4
Integrations
Connection to the ERP, CRM or logistics via the REST API or webhooks, stock and order synchronisation, accounting export.
- 5
Performance and security
Caching suited to dynamic pages (cart, account), query and image optimisation, CDN, properly sized hosting, backups, payment compliance and fraud protection.
- 6
Acceptance and launch
Test orders on every payment method, checks on shipping costs and taxes, training for your team on order management, then go-live and follow-up.

Why choose Agencei?
We develop, we do not just configure
When a feature does not exist, we code it with WooCommerce hooks rather than adding a tenth plugin that weighs the store down.
Performance from the design stage
A slow WooCommerce store loses sales. We handle queries, caching, images and hosting before launch, not after the first complaints.
Integration skills
We know how to connect WooCommerce to your ERP, CRM or logistics through the REST API, with error handling and retries.
Follow-up after launch
WooCommerce updates are frequent and sometimes breaking. We offer maintenance that tests them before applying.

Frequently asked questions
Is WooCommerce suitable for a large store?
Yes, provided the hosting is sized correctly, the database is well indexed, caching is appropriate and the number of plugins is limited. Very large catalogues or complex B2B needs require custom development, which we handle.
Which payment methods can you integrate?
Stripe, PayPal, bank solutions, instalment payments and mobile wallets, depending on your markets. We configure each gateway in test mode before switching to production.
Can WooCommerce be connected to my management software?
In most cases, yes, through the WooCommerce REST API and your tool's API, or through existing connectors when they are reliable. We study the flows (products, stock, orders, customers) before committing.
WooCommerce or PrestaShop for my store?
WooCommerce makes sense if you already have WordPress or if editorial content matters as much as the catalogue. PrestaShop is more focused on pure e-commerce and natively handles complex catalogues and pricing rules. We advise based on your team, catalogue and integrations.
Can you take over an existing WooCommerce store?
Yes. We start with an audit of the theme, plugins, database and hosting, then propose either targeted fixes or a rebuild if the store is too degraded.
